Effects of Air Pollution on the Agricultural Yield of Selected Crops in Nigeria

The effect of air pollution cannot be overemphasized, a research by EKIYOR, H.T of the Department of Laboratory Science, Ken Saro-wiwa Polytechnic Bori, Rivers state, Nigeria evaluated and showed the effects of air pollution on the agricultural yield of some selected crops in Eleme, Nigeria.

The researcher observed that concentration of sulphur dioxide (SO2), nitrogen oxides (NOx), ozone (O3) in the area exceeded the USEPA standards significantly. While suspended particulate matter (SPM) was slightly higher in all sampled locations.

It was observed that O3, SO2 and NO2 and SPM were the most significant air pollutants that adversely affected Cucumber, Cocoyam, Yam, Maize, Okro, Plantain, Cassava, Pumpkin and Pawpaw. Statistical analysis from the study showed that there was significant decrease in crop yield between the 2017/2018 harvest season and 2016/2017 harvest season (F = 20.3; p< 0.05; 95%Cl.) due to increased air pollution. The study revealed that air pollution causes approximately 38.3% crop losses annually.
